worked fine no feedback. Maybe the other guys did something wrong like running rca next to or over power wires no issues here.

Needed an amplifier to play holiday music out of 4 speakers, on a firetruck, from an mp3 player. It worked like a charm. Plenty loud enough for Santa & his helpers.

It's a cheapo. I don't recommend it, as it reproduces a substantial amount of electrical (alternator) noise.

not a very good product. The most electrical noise I have ever heard from an amp. These amps shouldn't be on the market.

Good amp overall, especially given the price. Since hooking this up to my speakers though, I have a high pitch ringing at lower volume (masked by higher volume) when the accelerator is engaged. Could be I'm not using a fuse in the power cable (at this price, 10A is an expensive fuse to install), but overall, not too shabby.

Well, I have to say for $34 it's a really good deal for someone who just wants a little more than a stock stereo.

I wanted more volume for when I'm going down the highway with the windows open. My '04 Dodoge Stratus SXT's stock system just didn't have the volume even when cranked up to "max" which is 38...it was really distorted.

With this amp, I can crank the stereo to about 25 and I can hear my music just fine doing 70+ down the highway.

It's not bridgeable, but who cares? It's REALLY easy to set up and puts out good, clean power. I don't think it's anywhere near 300 watts, but it's pretty loud.

I get some hum even when the stereo and amp are off, but nothing major at all. If you install an after market amp, it's gonna happen no matter who's name is on it.

Makes the BOSS CH6994 4-Way 4-Ohm 6-Inch x 9-Inch Poly Injection Cone Speakers I bought from Amazon along with the amp REALLY thump.

I can't complain for the price/performance.

Nuff said!

It sounded great of 1st, had enough power, but now buzzes quite a bit all the time, even with the volume completely down.

When I first bought it I installed it on my Chevy Tahoe. It sounded crap! The Clarion radio I installed had more power than this amp. Then I installed 2 other amps replacing this one, and none of those sounded OK. I took away the amp installed on my Jetta, which sounded AMAZING, with the same speakers and didn't even close to the way it sounded on the Jetta.
So I decided it was something with the acoustic on the Tahoe.
I bought another SUV and something happened to the amp I was installing, didn't wanted to power, so, with all cables running through the SUV and the speakers installed, pair of Kenwood 6x9 400 watts 4-way, and a Pyle 10" sub, just curious, I decided to install this Pyramid amp just to make at least some noise in my SUV, thinking it was going to sound crap.
What a surprise!
This small amp, really moved the speakers and sub! Sound is great, way ahead of expected.
Only con of this amp, it's that it's not bridgeable. But even do this, I bridged it to give it more power to the sub, and gave little more, and has functioned perfect for about 2 months now.
